Investors' Quality Tax-Exempt Trust (QUAL0178)

Objective

You can help build a better America with an investment in municipal bonds (bonds issued by municipalities to finance projects such as schools, roads and hospitals). Through one convenient investment in a unit investment trust, you can own a defined, diversified basket of municipal bonds.

Take advantage of federal tax-exempt investments through a convenient and efficient way of purchasing a professionally selected and diversified portfolio of quality municipal bonds. The trust is a long-term portfolio1 that offers tax-exempt federal income with the potential for higher yield than a portfolio holding insured municipal bonds. The bonds in the portfolio are generally not insured, and generally have credit ratings of at least A- by Standard & Poor's or at least A3 by Moody's as of the deposit date.

1 Due to the nature of municipal bonds, there is a risk that a bond may be called before maturity, potentially below the par value of the bond, and investors may be unable to reinvest their principal at the same rate of return.

2 A portion of your interest income may be subject to state or local taxes.

Diversification does not ensure a profit or eliminate the risk of loss.

Normal record dates and payable dates are the 10th and 25th calendar days monthly.

1Estimated current return (ECR) is based on the estimated annual income as a percentage of the current price of the units. Estimated long-term return (ELTR) is calculated using a formula which (1) takes into consideration and determines and factors in the relative weightings of the market values, yields (which takes into account the amortization of premiums and the accretion of discounts) and estimated retirement of all the bonds in the trust and (2) takes into account the expenses and sales charge associated with each trust unit. There can be no assurance that either the estimated current return or ELTR will be realized in the future and an investor's units, when redeemed, may be worth more or less than their original cost.

2The ELTR life represents the estimated life of the bonds in a Trust's portfolio determined for the purposes of calculating Estimated Long-Term Return.

3Estimated Annual Income Per Unit is as of close the most recent business day and is based on the estimated cash flows per unit. This amount will vary with changes in expenses, interest rates and the maturity, call or sale of bonds.

4Estimated Daily Rate of Accrual represents the annual interest from the securities within the portfolio divided by the number of days on which interest is calculated annually.

5Represents the principal amount of the underlying bonds per unit. Bonds may be sold to meet redemptions, to pay expenses, and in other limited circumstances. The sale of bonds will affect the principal amount of bonds included in the trust and as a result the principal amount of bonds per unit. There can be no assurance that a unitholder will receive this par value per unit in the future.

For Fixed-Income trusts, "S.F." indicates a sinking fund is established with respect to an issue of bonds.

The trust portfolio is provided for informational purposes only and should not be deemed as a recommendation to buy or sell the individual securities shown above.

There is no assurance that a unit investment trust will achieve its investment objective. An investment in this unit trust is subject to market risk, which is the possibility that the market values of securities owned by the trust will decline and that the value of trust units may therefore be less than what you paid for them. This trust is unmanaged. Accordingly, you can lose money investing in this trust.

An investment in a trust should be made with an understanding of the risks associated therewith, such as the inability of the issuer or an insurer to pay the principal of or interest on a bond when due, volatile interest rates, early call provisions and changes to the tax status of the bonds.

Investments in a trust may be subject to interest rate risk. If interest rates rise, the value of the bonds in a trust may decline and if interest rates decline the value of the bonds may increase. Also, the longer the period to maturity, the greater the sensitivity to interest rate changes tends to be.

A credit rating is an assessment provided by a nationally recognized statistical rating organization (NRSRO) of the creditworthiness of an issuer with respect to debt obligations, including specific securities, money market instruments or other debts. Ratings are measured on a scale that generally ranges from AAA/Aaa (highest) to D/C (lowest); ratings are subject to change without notice. For more information on Standard and Poor's rating methodology, please visit www.standardandpoors.com and select "Understanding Ratings" under Rating Resources on the homepage or Moody's at www.moodys.com and select "Rating Methodologies" under Research and Ratings on the homepage.

1The S&P and Moody's ratings apply to the bonds held by the trust, and not the trust itself.

A Standard & Poor's credit rating is a current opinion of the creditworthiness of an obligor with respect to a specific debt obligation. This opinion of creditworthiness may take into consideration the creditworthiness of guarantors, insurers or other forms of credit enhancement on the obligation.

Moody's municipal ratings are opinions of the investment quality of the issues and issues in the US municipal and tax-exempt markets. As such, these ratings incorporate Moody's assessment of the default probability and loss severity of these issuers and issues.

Historical Pricing

Distributions

From
to

BID PRICE Represents the net asset value per unit plus any remaining organization costs, deferred sales charge and creation and development fee. This price is not the purchase price of units and in many cases is not the price a unitholder would receive if the unitholder redeemed or sold units. Any remaining deferred sales charge payments are payable at the time a unit holder redeems or sells units.

LIQUIDATION PRICE Represents the value per unit that a unitholder would receive if the unitholder redeemed or sold units. This price is equal to the net asset value per unit plus any remaining organization costs and creation and development fee. This price reflects any remaining deferred sales charges payable in connection with a liquidation of units.

OFFER PRICE Represents the net asset value per unit plus any applicable organization costs and sales charges. This is the regular public offering price per unit paid to purchase units. This price is often subject to certain sales charge discounts described in a trust prospectus.

NET ASSET VALUE (NAV) Represents the value per unit of a trust's portfolio securities and other assets reduced by trust expenses and other liabilities, including remaining organization costs, deferred sales charges and creation and the development fee.

Performance data quoted represents past performance, which is no guarantee of future results. Investment returns and principal value will fluctuate and units, when redeemed, may be worth more or less than their original cost.

Returns are cumulative total returns (not annualized) unless labeled as average annual total returns. All returns reflect trust expenses as incurred and assume reinvestment of income and principal distributions, except for trusts that do not offer the option of reinvesting distributions into additional trust units. Please see the related trust prospectus for additional information. Returns do not reflect taxes.

A trust's performance, especially for short time periods, should not be the sole factor in making your investment decision. Please keep in mind that high, double-digit returns are highly unusual and cannot be sustained. Investors should also be aware that these returns were primarily achieved during favorable market conditions.

"Returns With Transactional Sales Charge" reflect the maximum transactional sales charge that would be payable by an investor upon sale or redemption of units at the end of the applicable period(s). The transactional sales charge includes any initial or deferred sales charges other than creation and development fee, if applicable. These returns do not reflect any creation and development fee prior to collection (generally the close of the initial offering period). Any creation and development fee, if applicable, is reflected in the returns as of the time of payment by a trust. These returns reflect any deferred sales charges only if the charges would be payable upon a unit sale or redemption at or prior to the end of the applicable performance period(s). Certain trusts are no longer offered for sale to the public and, as a result, do not publish an offer price or have a sales charge. In these cases, returns will not reflect a sales charge if a trust was not actually offered for sale to the public on the first day of the applicable period because units of the trust could not have been purchased by an investor at that time. These returns will show 'N/A' for "With Transactional Sales Charge" data.

"Returns Without Transactional Sales Charge" do not reflect any transactional sales charge and do not reflect any applicable creation and development fee prior to collection (generally the close of the initial offering period). Any creation and development fee, if applicable, is reflected in the returns as of the time of payment by a trust.

There is no assurance the trust will achieve its investment objective. An investment in this unit investment trust is subject to market risk, which is the possibility that the market values of securities owned by the trust will decline and that the value of trust units may therefore be less than what you paid for them. Accordingly, you can lose money investing in this trust. The trusts are unmanaged and their portfolios are not intended to change during the trusts' lives except in limited circumstances.

Estimated long-term return (ELTR) is calculated using a formula which (1) takes into consideration and determines and factors in the relative weightings of the market values, yields (which takes into account the amortization of premiums and the accretion of discounts) and estimated retirement of all the bonds in the trust and (2) takes into account the expenses and sales charge associated with each trust unit. There can be no assurance that either the estimated current return or ELTR will be realized in the future and an investor's units, when redeemed, may be worth more or less than their original cost.

2The ELTR life represents the estimated life of the bonds in a Trust's portfolio determined for the purposes of calculating Estimated Long-Term Return.

3Estimated Annual Income Per Unit is as of close the most recent business day and is based on the estimated cash flows per unit. This amount will vary with changes in expenses, interest rates and the maturity, call or sale of bonds.

4Estimated Daily Rate of Accrual represents the annual interest from the securities within the portfolio divided by the number of days on which interest is calculated annually.

5Represents the principal amount of the underlying bonds per unit. Bonds may be sold to meet redemptions, to pay expenses, and in other limited circumstances. The sale of bonds will affect the principal amount of bonds included in the trust and as a result the principal amount of bonds per unit. There can be no assurance that a unitholder will receive this par value per unit in the future.

There is no assurance that a unit investment trust will achieve its investment objective. An investment in this unit trust is subject to market risk, which is the possibility that the market values of securities owned by the trust will decline and that the value of trust units may therefore be less than what you paid for them. This trust is unmanaged. Accordingly, you can lose money investing in this trust.

An investment in a trust should be made with an understanding of the risks associated therewith, such as the inability of the issuer or an insurer to pay the principal of or interest on a bond when due, volatile interest rates, early call provisions and changes to the tax status of the bonds.

Investments in a trust may be subject to interest rate risk. If interest rates rise, the value of the bonds in a trust may decline and if interest rates decline the value of the bonds may increase. Also, the longer the period to maturity, the greater the sensitivity to interest rate changes tends to be.

A credit rating is an assessment provided by a nationally recognized statistical rating organization (NRSRO) of the creditworthiness of an issuer with respect to debt obligations, including specific securities, money market instruments or other debts. Ratings are measured on a scale that generally ranges from AAA/Aaa (highest) to D/C (lowest); ratings are subject to change without notice.
